Sababta abkaaga iPhone u muujiyo hal IP uuna serverku diiwaangeliyo mid kale
Cinwaanka is-dhexgalka, barta dambe ee socket iyo isha uu serverku diiwaangeliyo waxay ka jawaabaan su'aalo kala duwan. VPN waxay ku dartaa macne; kama dhigto hal lambar.
Waxaa yimaada tigidhada taageero oo sheegaya in abku uu muujinayo hal cinwaan halka uu serverku diiwaangeliyay mid kale, ka dibna way weydiiyaan kee baa been sheegaya. Midkoodna ma aha; kuwani waa laba indha-indhayn oo laba shay oo kala duwan. Cinwaan ku xidhan is-dhexgal, cinwaan ku xidhan socket, iyo cinwaan isha oo ay aragto adeeg fog ayaa ka jawaaba saddex su'aalood oo kala duwan. VPN waxay telefoonka ku dartaa macne shabakadeed waxayna u wada geyn karin saddexdaas hal lambar oo qalabka oo dhan ah. Akhri magacyada goobaha tigidhka ka hor intaadan akhrin cinwaannada.
Waxa tigidhku sida caadiga ah qeexo
Qiyaas telefoon Wi-Fi ku jira oo tunnelkiisu sarreeyo. Is-dhexgal Wi-Fi waxa uu hayaa cinwaan LAN, is-dhexgal tunnel-ku waxa uu hayaa cinwaan gudaha oo la qoondeeyay, codsiga ka soo baxa tunnel-ka waxa uu ku gaadhaa adeeg dadweyne isha kasta oo ka badbaadda tarjumaad kasta oo jidka ku timid. Abka daabaca cinwaanka gudaha iyo serverka diiwaangeliya isha la tarjumay labaduba si sax ah bay wax u sheegaan, labada qiime-na waligood isku mid ma noqon doonaan.
Saddexda indha-indhayn waxay ku kala duwan yihiin waxa ay caddayn karaan, ma aha oo kaliya waxa ay qeexaan.
| Observation | What it describes | What it cannot prove |
|---|---|---|
| An address on a local interface | One configured attachment: Wi-Fi, cellular or a tunnel | The source a remote site receives |
| A socket's local endpoint | The binding used by that one connection | The address after translation further along |
| The peer address at a service | What arrived at that observation point | Any other interface on the phone |
Miiskaas ku hay meel u dhow koodhka qiimayaashan tigidhka ku buuxiya, sababtoo ah jahawareerka ugu badan halkan waa is-dhaafista tiirarka ma aha cillad shabakadeed.
Waxa wicitaanka socket ka jawaabi karo iyo waxa uusan ka jawaabi karin
Heerka API, getsockname waxa uu soo sheegaa barta dambe ee maxalliga ah ee hadda ku xidhan socket gaar ah. Socket isku xidhan, taasi waa isha uu karnalku u doortay xiriirkaas, taas oo horey uga gaar ah liis kasta oo is-dhexgal. Tani ma aha raadinta cinwaan dadweyne, wicitaankeedana socket aan xidhnayn waxba kuma sheego. Wax kasta oo ay soo celiso dib ayaa loo qori karaa mar dambe jidka, sidaas darteed kaliya indha-indhaynta adeegga laftiisa ayaa awood u leh waxa adeeggu helay.
Apple platformyada dhinaca is-dhexgalku waxa uu leeyahay dushiisa gaar ah: dejinta tunnel-ku waxa ay taxdaa cinwaannada loo qoondeeyay is-dhexgal tunnel-ka. Akhrintooda waxa ay kuu sheegtaa sida tunnel-ka loo habeeyay, kumana sheegto jidka uu codsi gaar ah qaaday, sababtoo ah habaynta iyo xeerarka ab kastaa waxay tan u go'aamiyaan xiriir kasta.
Tunnel kala qaybsan waxa uu farqiga muujiyaa. Hal codsi waxa uu ka soo bixi karaa tunnel-ka halka kan xiga, oo loo jeediyay meel kale ama qoys cinwaan kale, uusan ka soo bixin, sidaas darteed laba natiijo oo isla ab ah oo ilbiriqsiyo kala duwan waa daacad oo kala duwan yihiin.
Dooro indha-indhaynta su'aasha la jaanqaadaysa
Si ula kac ah u dooro halkii aad wax walba cabbiri lahayd. Waxa backend-ku arko, isha ku diiwaangeli backend-ka, meesha proxy rogan uu hor yaallona, cinwaanka macmiilka ka akhri madaxa gudbinta ee hirgelintaadu si dhab ah u dhigto, ma aha wax macmiilku soo diray.
Si aad u ogaato haddii tunnel-ku habaysan yahay, akhri is-dhexgalka. Si aad u ogaato haddii taraafikada abkani isticmaalay, ka dir taraafik abkaas oo u jeedi meel aad maamusho oo isbarbardhig isha labada daraf.
Xeerarka ab kastaa waxay mudan yihiin jumlad u gaar ah. Natiijada browser-ku waa caddayn ku saabsan browser-kaas, tunnel la maamulo oo ab kastaa waxa uu laba ab ku ridi karaa isla telefoon jidar kala duwan isla daqiiqaddaas. Xaqiijinta daboolka waxa ay ka dhigan tahay in taraafik laga diro abka la hadlayo, qoyska cinwaanka la hadlayo.
Magacyada is-dhexgalku ma aha qalab wax sheega
Sidoo kale ha u isticmaalin magac is-dhexgal hubin VPN. Magacyadu ma aha heshiis dadweyne, telefoonna waxa uu yeelan karaa dhowr xiriir halka midkood oo kaliya uu qaado codsigaaga.
U bixi goobta magaca indha-indhaynta ay haysato. local_interface_address, socket_local_endpoint iyo service_observed_source waa qallafsan yihiin oo aan madmadow lahayn, madmadow la'aantaana waa waxa aad rabto marka qiimuhu toddobaad kadib ku dhaco tigidh taageero. Hal tiir oo la yiraahdo device IP ayaa saddexda soo ururin doona kadibna loo aamin doonaa sida mid oo kale.
Aqoonsiga ka fogee tiirka cinwaanka
Bixidda VPN la wadaago ma aha aqoonsiga isticmaalaha, cinwaan gaarna ma aha aqoonsiga gelitaanka. Labaduba waxay qeexaan jid ma aha qof, midkoodna sida aqoonsi u qaadashaduna waxay shil habayn u beddelaysaa go'aan ogolaansho.
Marka qof weydiiyo cinwaanka telefoonku leeyahay, jawaabta waxtarka leh waa su'aal ku saabsan xiriirka kee iyo goobjoogaha kee. Qeexitaanka getsockname waa mudan in la xigto kiiska dhexe, sababtoo ah waxa uu xalliyaa su'aasha socket isagoon isku dayin in uu xalliyo labada kale.
Kadib qor saddexda midka ay alaabtaadu si dhab ah u muujinayso, labada kalena ka tirtir is-dhexgalka.
